UNITED STATES PATENT OFFICE.

ALBERT N. PUTNEY, OF PALMYRA, NEW YORK, ASSIGNOR OF ONE-FOURTH TO IRA M. LUDINGTON, OF ROCHESTER, NEW YORK, AND ONE-FOURTH TO WILLIAM L. KNAPP AND ONE-FOURTH TO EDWARD 0. NORTH, OF PALMYRA, NEW YORK.

DUMPING-WAGON.

To all whom it may concern:

Be it known that I, ALBERT N. PUTNEY, a citizen of the United States, and a resident of Palmyra, in the county of Wayne and State of ew York, have invented a new and Improved Dump-Wagon, of which the following is a specification.

My present invention has for its object the production of a dump Wagon in which there shall be a normal tendency for the parts of the wagon to close when empty and in which also there shall be a normal tendency of such parts to open when loaded in order that but little effort may be required to operate the wagon.

Another object of my invention is to provide a dump wagon embodying the above advantages and in which also the load carrying elements of the box shall be pivotallysupported in suitable bearings and each section adapted to be operated from practically a fixed center, in order that such dumping elements may be operated from a crank or lever secured to the center of motion of such parts and actuated by means of mechanism under the control of the operator.

With these objects in view, my invention comprises a Wagon in which the load carrying elements consist of two quadrantal sections, each independently and pivotally supported at each end by means of a trunnion upon which such parts may swing to open and close. The pivotal points of these quadrantal sections are so located that there is a tendency on the part of such sections when empty to close and when loaded to open and discharge the load.

In order that the ends of the quadrantal sections in my wagon may be made of moderate thickness without springing, I have found it desirable to provide tracks for sustaining a large part, at least, of the load of the Wagon and having a curvature concentric with the axis of the pivotal support for the uadrantal sections, and cooperating with t ese tracks I provide rollers adapted to sustain, to a large extent at least, the Weight of the load. In carrying out my invention in this respect, I prefer that the rollers be attached to the quadrantal sections and that the tracks be supported from the main frame of the wagon, although this arrangement may be reversed without departing from the spirit of my invention.

The accompanying drawings showing only such parts of a dumping wagon as are necessary to illustrate my invention as embodied therein, are as follows :Figure 1 is a top or plan view. Fig. 2 is a side view and Fig. 3 is a front end view of only the right hand or lower uadrantal section, as seen in Fig. 1. Fig. 4 s ows the mechanism for operating the latches Z to unload the wagon. Fig. 5 is a rear end view and Fig. 6 is a front end view of the wagon. Fig. 7 is a rear end view of a modified form of my wa on and Fig. 8 is a side view of the rear end t ereof.

As the running gear forms no part of my present invention, it is not shown in the drawings.

Similar letters refer to similar parts throughout the different figures of the drawings.

Referring to the drawings,-C C are channel beams comprising the side members for the frame of my wagon connected together at the rear end just forward of the hopper or wagon body by means of eye beams I and P. On these eye beams I and I are secured bearings c, as indicated, to receive the trunnions 16 carried by plates 29 secured to the ends of the quadrantal sections B and B The eye beams I are trussed on the under side in the well known way by means of the strap V and member 1), and constitute supporting members for the trunnions t. The trunnions t at the forward end of the quadrantal sections are extended through and beyond the bearings c to receive the crank levers a. Connecting links a articulate with the outer ends of these levers a and have their lower ends articulating with the outer end of a lever or crank arm a secured upon the rear end of the shaft e revolubly supported in bearings secured to the under side of the T-beams i and 2' extending transversely between the channel beams C.

On the forward end of the shaft e is secured a bevel gear 9 meshing with asimilarbevel gear 9 carried on the end of the shaft (3 nearest the center of the wagon, and this shaft 6 is revolubly supported in bearings secured to the under side of the T-beams j and 1' extending between the T-beams i and i and secured thereto. On the outer end of this shaft e is secured an operating lever h having a handle at its upper end, as indicated.

On the under side of the quadrantal sections B and B are secured bearing plates d having the rollers r revolubly supported therein, and these rollers r are arranged to ride upon tracks T supported transversely of the wagon by means of braces S secured to the under side of the channel beams 0. Of these tracks T and their corresponding rollers 9 there may be any desired number according to the length of the wagon body. In the drawings I have shown two such tracks so arranged as to sustain nearly the entire weight of the load and relieve, to a very great extent, the strain upon the trunnions t, which serve, under these conditions, more as a guiding means than as a means for sustaining the load. The tracks T have segmental surfaces upon which the rollers r operate and these segmental surfaces are arranged concentric with the axes of the trunnions t.

In Figs. 5 and 6 the open positions for the quadrantal segments B and B of the wagon are indicated in dotted lines at B and B respectively and the corresponding positions for the bearing plates (1 and rollers r are indicated in dotted lines at d and 1 respectively. The upper edge of the side member for each quadrantal section is formed around into a roll 0 to stiffen the same, and this roll at the upper edge of each quadrantal section B and B is engaged, as indicated, by latches l secured upon rods a working in ears 7c secured on top of the channel beams C, the arrangement being such, as indicated in Fig. 4, that the operation of the handle m serves to release the latches 1 from the rolls 0 at the up er edges of the sections B and B in the fol owing way, viz :to release the latches Z the handle m is raised and the left hand rod n as seen in Fig. 4 is turned thereby to release the latches Z carried thereby from the roll 0 on the left hand section B. This left hand rod n carries a lever 8. connected by a link 8 to the lower end of a lever 8 pivotally supported at its center on a post f secured to the top of the eye beam I and having its upper end connected by a link 5 to the outer end of a lever s secured on the right hand rod n, whereby the latches Z on the right hand rod n are operated simultaneously with those on the left hand rod 7. It is desirable to provide these latches Z in order that the levers a and the links a and the parts connected thereto may be relieved from the strain and jar in holding the wagon closed. The normal position for the latches Z is in engagement with the rolls 0 on the sections B and B and holding the segments of the box closed. Corner blocks a are used, as indicated, where they serve to rigidly connect the parts. The eye beam I may be connected across and between the channel beams C on their under receive the connecting mechanism for the fifth wheel.

The operation of the segments of my wagon by means of the lever and handle it is believed to be so obvious as to call for no further description herein.

Refer'now to Figs. 7 and 8, in the modification of my invention therein shown, at each end of the sections B and B are secured trunnion plates p having trunnions t, as already described, at their upper ends. These trunnion plates p have revolubly supported on studs projecting outwardly from their lower ends rollers 9 adapted to engage the track plates T and sustain the greater part of the load in the wagon. These track plates T are supported by straps S as indicated, from the rear end of the channel beams C. In other respects, this modification of my wagon is the same as that already above described and the operation thereof is substantially the same also.

The sections B and B of my wagon may be trussed in the manner clearly indicated in Figs. 2, 5, 6 and 7 by means of truss rods to secured to the ends of such sections, as indicated, and under the struts w located at approximately the center of the sections B and B The righthand quadrantal section B carries an overlapping flange b to cover the joint between such section B and the section B.

What I claim is 1. In a dump wagon; two similar sections pivotally supported with their axes of rotation fixed and disposed longitudinally of the wagon, each section having its side wall formed to an uninterrupted and practically uniform curvature, such sections each conformed relatively to its axis of su port to approximately balance the latera thrust or wedging action of the load, such sections so conformed relative to their axes of rotation that their centers of gravity when loaded fall between such axes of rotation and outside of such axes of rotation when empty.

2. In a dump wagon; two quadrantal sections adapted when closed to form a semi cylinder, each one of such sections pivotally supported to swing upon a fixed axis; cooperatmg tracks and rol ers for supporting such sections, each one of such tracks presenting to the cooperating roller a segmental surface arranged concentrically with the axis of the pivotal support for the corresponding section.
